AR-15 ARMORER'S WRENCH Reviews & Ratings

Multiple Tools In One - You'll Always Want It Close By!

You'll find yourself reaching for the Brownells Armorer's Wrench a lot when you're working on AR-15s. The standard 6-pin barrel nut wrench works on both peg-style and encapsulated barrel nuts. The "can’t slip" 4-pin castle nut wrench enables secure installation and removal of M4-carbine type receiver extensions. (NOTE: the stock must be removed so the castle nut wrench can be slid over the buffer tube to access the nut.)

There's a cutout for an A2 receiver extension nut, another cutout for a 1/2" torque drive, and slots for 5/8" and 3/4" wrench flats on flash hiders and muzzle brakes. Of course, our armorer's wrench has the last-a-lifetime quality you expect from Brownells tools: heavy-duty steel construction, precise dimensions, and a comfortable anti-slip matte finish.

Not a good wrench

AR-15 build and maintence. Nothing great about it at all for the price. Well not fit the AR-15 barrel nut, slips and damages the nut.
